Abstract Three-layer gelatin films, composed of sodium montmorillonite (MMt) – plasticized gelatin (Ge-5MMt) (inner layer) and dialdehyde starch (DAS) – cross-linked and plasticized gelatin films (Ge-10DAS) (outer layers), obtained by heat-compression molding, were submitted to degradation under indoor soil burial conditions for 14 days. Biodegradation of multilayer film as well as individual components and control gelatin films was evaluated by monitoring water absorption and weight loss. It was established that technological treatments performed on gelatin, such as cross-linking, compounding with clay and heat-compression molding have a major impact on the biodegradation rate and extent. The possible reasons are discussed. Weight loss results revealed that the susceptibility to microbial attack during soil burial varied in the order: Ge-10DAS
